谈论的目的是碳化对混凝土的影响主要并不是强度,因为只要把水胶比降低到一定程度,掺了粉煤灰的混凝土28天抗压强度是会满足设计要求的,再由于掺了粉煤灰的混凝土受到现场温度的影响,浇筑的混凝土实际强度会比标准养护的相同的混凝土试件强度高,且与碳化无关。 Talking about the purpose of carbonation is not the main impact on the concrete strength, because as long as the water-cement ratio reduced to a certain extent, mixed with fly ash concrete 28 days compressive strength will meet the design requirements, and then mixed with pulverized coal Gray concrete is affected by the temperature of the site. The concrete strength of pouring concrete is higher than that of the same concrete specimen with standard curing, and has nothing to do with carbonization.
